HAL FLASH Generic Driver
2. Interrupts and flags management functions :
In addition to these functions, this driver includes a set of macros allowing to handle the
following operations:
Set the latency
Enable/Disable the prefetch buffer
Enable/Disable the Instruction cache and the Data cache
Reset the Instruction cache and the Data cache
Enable/Disable the FLASH interrupts
Monitor the FLASH flags status
18.2.3

Programming operation functions

This subsection provides a set of functions allowing to manage the FLASH program
operations.
This section contains the following APIs:
HAL_FLASH_Program()
HAL_FLASH_Program_IT()
HAL_FLASH_IRQHandler()
HAL_FLASH_EndOfOperationCallback()
HAL_FLASH_OperationErrorCallback()
18.2.4

Peripheral Control functions

This subsection provides a set of functions allowing to control the FLASH memory
operations.
This section contains the following APIs:
HAL_FLASH_Unlock()
HAL_FLASH_Lock()
HAL_FLASH_OB_Unlock()
HAL_FLASH_OB_Lock()
HAL_FLASH_OB_Launch()
18.2.5

Peripheral Errors functions

This subsection permits to get in run-time Errors of the FLASH peripheral.
This section contains the following APIs:
HAL_FLASH_GetError()
FLASH_WaitForLastOperation()
244/1371
Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
HAL_FLASH_Lock() functions
Program functions: byte, half word, word and double word
There Two modes of programming :
Polling mode using HAL_FLASH_Program() function
Interrupt mode using HAL_FLASH_Program_IT() function
Handle FLASH interrupts by calling HAL_FLASH_IRQHandler()
Wait for last FLASH operation according to its status
Get error flag status by calling HAL_SetErrorCode()
